Device and connection control method

Abstract

In a device connected wirelessly with a host, a host identification information holding unit holds identification information of the host. A connection control unit of the device searches for an identification signal including the host identification information transmitted from the host, where the search is for connecting with the host at a predetermined time interval until the search is succeeded. The host may be a wireless USB (WUSB: Wireless Universal Serial Bus) host. In such case, the connection control unit performs a search for a MMC (Micro-scheduled Management Command) from the wireless USB host.

1 . A device connected wireless with a host to be used comprising:
 a host identification information holding unit to hold identification information of the host; and   a connection processing unit to search for an identification signal including the host identification information transmitted from the host, the search being for connecting with the host.   
   
   
       2 . The device according to  claim 1 , wherein the connection processing unit performs the search at a predetermined time interval. 
   
   
       3 . The device according to  claim 1 , wherein the host is a wireless USB (WUSB: Wireless Universal Serial Bus) host, and
 the connection processing unit performs a search for a MMC (Micro-scheduled Management Command) from the wireless USB host.   
   
   
       4 . The device according to  claim 2 , wherein the host is a wireless USB (WUSB: Wireless Universal Serial Bus) host, and
 the connection processing unit performs a search for a MMC (Micro-scheduled Management Command) from the wireless USB host.   
   
   
       5 . The device according to  claim 1 , further comprising a mode setting unit enabling to specify a manual mode and automatic mode,
 wherein the connection processing unit performs the search only by an instruction for the search in case of being configured to the manual mode, and   the search is performed intermittently until the search is succeeded in case of being configured to the automatic mode.   
   
   
       6 . The device according to  claim 2 , further comprising a mode setting unit to enable specifying a manual mode and an automatic mode,
 wherein the connection processing unit performs the search only by an instruction for the search in case of being configured to the manual mode, and   the search is performed intermittently until the search is succeeded in case of being configured to the automatic mode.   
   
   
       7 . The device according to  claim 1 , wherein the connection processing unit, after succeeding the search, continues requesting for a connection within a predetermined length of period until a connection is allowed by the host. 
   
   
       8 . The device according to  claim 7 , wherein the host identification holding unit holds identification information of a plurality of the hosts, and
 the connection processing unit, after succeeding the search for one of the plurality of the hosts, in case a connection is not allowed by the host in the predetermined length of time, a connection request for the host is stopped and the search is performed for another host among the plurality of the hosts, identification information of the plurality of hosts being held by the host identification information holding unit.   
   
   
       9 . A method to control connections for a device connected wirelessly with a host to be used, comprising:
 performing intermittently a search for an identification signal including identification information to identify a host transmitted from the host until the search is succeeded, the search being for connecting with the device.   
   
   
       10 . The method according to  claim 9 , wherein the search is performed at a predetermined time interval. 
   
   
       11 . The device according to  claim 9 , wherein the host is a wireless USB (WUSB: Wireless Universal Serial Bus) host, and
 the search is for a MMC (Micro-scheduled Management Command) from the wireless USB host.   
   
   
       12 . The device according to  claim 10 , wherein the host is a wireless USB (WUSB: Wireless Universal Serial Bus) host, and
 the search is for a MMC (Micro-scheduled Management Command) from the wireless USB host.   
   
   
       13 . The method according to  claim 9 , wherein a manual and automatic mode can be specified,
 the search is performed only by an instruction for a search in case of being configured to the manual mode, and   the search is performed intermittently until the search is succeeded in case of being configured to the automatic mode.   
   
   
       14 . The method according to  claim 10 , wherein a manual and automatic mode can be specified,
 the search is performed only by an instruction for a search in case of being configured to the manual mode, and   the search is performed intermittently until the search is succeeded in case of being configured to the automatic mode.   
   
   
       15 . The method according to  claim 9 , wherein after the search is succeeded, a request for connection is continued until a connection is allowed by the host. 
   
   
       16 . The method according to  claim 10 , wherein after the search is succeeded, a request for connection is continued until a connection is allowed by the host. 
   
   
       17 . The method according to  claim 15 , further comprising:
 holding identification information of a plurality of the hosts, wherein after the search is succeeded for one of the plurality of the hosts, in case a connection is not allowed by the host within the predetermined length of period, a connection request for the host is stopped and the search is performed for another host among the plurality of the hosts.   
   
   
       18 . A host connected with a device to be used, comprising:
 a connection processing unit to allow for a connection with a device requesting for a connection under a condition application software implemented to the device is requesting to use the device.   
   
   
       19 . The host according to  claim 18 , wherein the connection processing unit, after allowing for a connection, at an end of the usage of the device by the application software, disconnects the device. 
   
   
       20 . The host according to  claim 19 , wherein the connection processing unit connects or disconnects with the device according to a usage request or a disconnection request for the device issued from the application software.
